With the latest upgrade of ready API to 1.8.0, my previous xpaths do not work.

I was using the XML response of a JDBC request  as an input to another rest step using the 'Get data' option 

Previously it used to create an xpath like  ( '${Get some value#ResponseAsXml#//Results[1]/ResultSet[1]/Row[5]/COLUMN_ONE[1]}' )" (in version 1.7.0)

But now, it doesn't work.

If I change the casing of COLUMN_ONE to column_one in above xpath, it starts working otherwise it throws an error

{"message":"Unexpected character (',' (code 44)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')\n at [Source: java.io.ByteArrayInputStream@54bd3f5b; line: 2, column: 19]"}

 Please suggest a workaround, as i have lots of JDBC requests in my project and changing the letter cases in all xpath requests would be a huge pain.
